The said frame tional view through the frame or holder or holder is adapted to beheld in such a having the impact members applied thereto position by a set screw 8 having threaded 5 and showing the manner of attachment to engagement with a suitable aperture in the thepicker stick, the latter being shown in back wall 6 of the socket, the said set screw dotted lines; impinging against the rear face of the picker stick. The lower edges of the rear side walls 5 are preferably slightly tapered towards the back wall 6. Any other form of fastener may be substituted for the set screw.

Adapted to be fitted between the spaced,

open-ended side walls 3 and to be introduced with the same and adapted to bear above and below the upper and lower edges respectively of said walls, as clearly shown in Figure l of the drawing, to rigidly hold the same in position, one upon the other, within the space between the walls 3, the outermost filler being in posit-ion to contact with the nose of the shuttle, in the usual manner. Each filler is substantially I-shaped.

The rear wall 4 is provided at its top and bottom edges with integral ears 4 having suitable apertures for the reception of split keys 11, which also traverse apertures 9 formed centrally near the top and bottom of each filler 9 and so located as to-aline with the apertures of the ears 4*. the split key or cotter pin is adapted to bear against the rear face of the ears 4, and the prongs are bent oppositely against the front face of the outermost filler to hold'the entire series in place, the location of the pins being such as to be out of the path of the nose of the shuttle.

When the outermost filler has become worn by the pointed end of the shuttle forming a conical opening in the same, it is only necessary to reverse the fillers, or to place a rear one in front, or to discard the worn one and replace the same by a new "one, which, operation ma be quickly accomplished by stopping t e machine only-for a few moments, thus resulting in a great sav- -ing.- It will be seen that the filler members are held in position in the frame or holder by the cotter pins 11 and that the impact of the fillers with the end of the shuttle assists in holding them in place.

, The modified form of the invention illustrated in Figures 5, 6, 7 and 8 is adapted for use in a loom whereinthe picker, while actuated by the picker stick, in the usual mannor, is further provided with a guiding means to insure the picker moving bodily in a horizontal direction. A holder frame 12 formed of a metal casting, preferably, is provided, near one' The loop of side, with a rectangular, verticallydisposed opening 13 for the passage of the picker stick 141 which may be of the usual construction and operated in the usual manner, the opening being larger than the stick to allow the latter to oscillate. At one side of the opening 13 the holder is provided with a tubular bearing bore orpassage 15 extending from front to rear of the holder and adapted to slide back and forth on a hori- 7'5 zontally disposed guide bar 16 suitably secured to and forming part of the loom struc-- ture.

At the side of the picker stick opening 1-3 opposite the guide rod bearing 15, the frame 12 is provided with a horizontal, transverse extension 17 comprising a filler-holder, open at the front end directed towards the shuttle andopen at the top and bottom, the outer wall 18 being connected to the body portion of theframe by a rear 'wall 19 which is provided on its .upper and lower edges with integral, apertured ears 20 similar to the ears of the first described form of the invention. a

The opposed inner and outer faces of the seat defined by the body of the frame and the outer wall 18 are slightly dove-tailed as shown in Figure 8 and are adapted to receive between them the fillers 21 in the same manner as heretofore described, the fillers being adapted to be expanded laterally to fill the dove-tail recess as they are effected by the repeated blows" of the shuttle.

The fillers 21, which are formed of any of the mentioned materials, are provided with oustanding lugs 22 at their upper and lower corners, which rest against the upper and lower edges of the body of the frame and the outer wall 18, and prevent any ver- 1'05 tical movement of the same in the holder. and the said fillers are further providedwith apertures near their top and bottom edges, said apertures being in a-linement with 'the apertures of the ears 20 when the fillers are seated and adapted to receive split keys or cotter pins 23 to hold the fillers from forward movement in their seats. a

The first described form of the invention is us'ed in looms where the oscillating picker 'st1ck,1s in the path of movement of the the picker stick, to be actuated thereby, and I having vertically disposed fillers carried by the frame in such manner as to expose the foremost filler to be engaged by the shuttle,

the said fillers being readily interchanged or renewed. I y Y aeaass From the foregoing, it will be seen that a simple, cheaply manufactured and easily-installed picker for looms has been provided, which may be applied to any picker stick, and that the same may be quickly renewed at any time by the simple replacement of the filler members, which may be cheaply manufactured and sold at a low cost.

\Vhat is claimed is 1. A picker for looms comprising a frame or holder provided with spaced, vertically disposed walls joined at their rear edges by a transverse wall having an apertured lug or ear at its top and bottom edges and defining a filler seat, said frame having a vertically disposed picker stick opening passing entirely through the same adjacent to the filler seat, and a plurality of fillers fitting in the seat and extending to the front edges of the spaced walls, said fillers having outstanding corner, lugs bearing on the top and bottom edges of the spaced walls to prevent vertical displacement of the same, each filler being substantially I-shaped.

2. A picker for looms com rising a frame or holder formed to provi de spaced side walls, a transverse wall connecting the side walls at one end, a vertically disposed socket adapted to surround a picker stick and having a fastening means for the same, and a plurality of fillers equal in width to the space between said spaced walls and adapted to snugly fit between and extend above and below the same and bear against the transverse wall, said fillers each having outstanding lugs at each corner to overhang and abut against the upper and lower edges of the spaced side walls.

3. A picker for looms comprising a'frame or holder formed to provide spaced side walls, a transverse wall connecting the side walls at one end, perforated lugs extending upwardly and downwardly from the top and bottom edges of the transverse wall, a vertically disposed socket adapted to be traversed by a picker stick, and a plurality of fillers adapted to fit between and extend above and below the spaced walls of the holder and having recesses in their side edges for the reception of the same, said fillers being provided with apertures to aline with the apertures of the said lugs, and

fastening pins or keys engaging the ears and apertures in thefillers to hold the fillers in place.

In testimony, that I claim the foregoing as my own, I have hereto affixed my signature.
